X-Ray Deck for Mental Effects Yaya! Hersteller Harris, Paul YIN & YANG esse has transformed a simple house-hold item into the world's teeniest invisible hold-out. And it just happens to work really really well with your normal Sharpie cap! With your tiny YAYA in place you can take the cap off your Sharpie and make it instantly vanish and re-appear in your other hand...or poke the cap into one ear and pull it out the other. You can "snort" the cap up your nose then sneeze it back into your hand. YAYA even makes a poker chip vanish, appear or transform! YAYA also lets you perform the perfect Torn And Restored (and Signed) Bill. Just borrow a bill roll it into a ball, tear the ball in half, touch the two halves together for an instant full-view no-cover restoration! The signed bill is immediately handed back for examination. × Yaya!
